The zone-blocking running scheme and offensive coordinator Greg Knapp are gone, but Raiders right guard Mike Brisiel was able to keep his job by agreeing to a pay cut Monday. Brisiel, who was signed a year ago to a five-year, $20 million deal, now will make $1.35 million in base salary for 2013 instead of $4.35 million, a league source confirmed.

The Raiders are roughly $1.5 million under the $123 million salary cap, and they don't have to make any decisions on high-priced players such as defensive tackle Tommy Kelly and receiver Darrius Heyward-Bey before free agency starts next Tuesday.

Brisiel was a disappointment in a 4-12 season in which Oakland finished 28th in rushing at 88.8 yards per game. He had offseason ankle surgery, and the 6-foot-5, 310-pounder probably would have been cut if he didn't agree to a pay cut.

Brisiel, 29, could lose his starting job, anyway. He was signed because of his success in the Houston Texans' zone-blocking scheme. Lucas Nix, a 6-5, 320-pound second-year player from the University of Pittsburgh, could be the first option as the Raiders switch to a more straight-ahead, power scheme.

-- Ravens quarterback Joe Flacco signed a contract worth $120.6 million over six years, making him the highest-paid player in NFL history. The Super Bowl MVP will receive a $29 million signing bonus and $52 million in guaranteed money. He will be paid $51 million over the first two years of the deal.
